Environmentally friendly tire reclaimed rubber is non-polluting, non-radioactive, non-penetrating, non-hazardous substances on the human body reclaimed rubber tires, belonging to special reclaimed rubber. Commonly used in the production of export-oriented rubber products. There are many testing standards for green tire reclaimed rubber. The most commonly adopted by the international community is the EU ROHS Environmental Protection Directive and the SGS Quality Environmental Certification System.
1, ROHS six hazardous substances detection: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) a total of six substances.
Heavy metals: cadmium and cadmium compounds Cd, lead and lead compounds Pb, mercury and compounds Hg, hexavalent chromium compounds Cr.
Organic bromine compounds: Polybrominated biphenyls PBBs, Polybrominated diphenyl ethers PBDEs.
In addition, the following new restricted substance tests are included: Phthalates, PAHs, TBBP-A, PFOS, PFO, PFO, Nonyl Phenol (NP), Benzotriazole, Halogen, Volatile organic compounds such as VOC.
2, REACH testing: European chemicals registration, assessment, licensing and restrictions laws and regulations.
3, SVHC high concern substances: highly concerned about the material, from the EU REACH regulations. According to Article 57 of the REACH Regulation, SVHC is determined according to the following criteria. Substances of very high concern matter, the consequences of serious harm.
4, PAHS test: refers to a class of two or more benzene ring of a class of organic compounds. Polycyclic aromatic hydrocarbons are hydrocarbons containing more than two benzene rings in the molecule, including more than 150 compounds such as naphthalene, anthracene, phenanthrene and pyrene.
PFOS Test: It consists of fully fluorinated anions in perfluorinated acid sulfuric acid and exists as anions in salts, derivatives and polymers.
6, Norway POHS: Consumer products ban certain hazardous chemicals requirements, saying it will limit 18 kinds of consumer goods, namely PoHS regulations. The 18 substances that are restricted are HBCD, tetrabromobisphenol A, medium chain chlorinated paraffins, lead and lead compounds, cadmium and compounds, arsenic and compounds, tributyltin compounds, triphenyltin compounds, Musk ketone, perfluorooctanoic acid and salts and esters, surfactants DTDMAC, DODMAC / DSDMAC, DHTDMAC, bisphenol A, diisooctyl phthalate, pentachlorophenol and triclosan. Substances to be restricted are characterized by persistence, bioaccumulation and / or toxicity.
PoHS has a total of 10 hazardous substances: MCCP, bisphenol A, xylene musks, triclosan, perfluorooctanoic acid, hexabromocyclododecane, pentachlorophenol, lead and its compounds, cadmium and its compounds, arsenic And its compounds.
7. Phthalates test: In the EU, the 1999/815 / EEC directive issued in 1999 shows that among PVC-related children's toys and related articles put in the mouth of three-year-old children, six plastic The agent must not exceed the limit of 0.1% (six plasticizers are: 2-ethylhexyl phthalate DEHP, di-n-butyl phthalate DBP, butyl benzyl phthalate BBP, Diisononyl phthalate DINP, diisodecyl phthalate DIDP and di-n-octyl phthalate DNOP.
8, Halogen: Including fluorine (F), chlorine (Cl), bromine (Br), iodine (I), 砹 (At), referred to as halogen. As 砹 is a radioactive element, so often referred to as halogen only refers to: fluorine, chlorine, bromine and iodine. Halogen is widely used in flame retardants, refrigerants, solvents, organic chemical raw materials, pesticide pesticides, bleach, wool skim and so on.
These tests are reclaimed rubber often used test standards and related testing projects, different rubber products of different performance, use different test items are also different, the customer needs according to their needs to select the required test rubber.
